Species richness and macronutrient content of wawo worms (Polychaeta, Annelida) from Ambonese waters, Maluku, Indonesia
The aims of this research were to: (1) investigate the species richness of wawo worms, and to (2) analyze macronutrient content of the worms. Wawo worms were sampled using a fishing net on March 18(th)-19(th), 2014, from Ambonese waters, Maluku. As many as 26 wawo species belonging to 5 families were identified. Palola sp. was identified as the most abundant species of wawo, followed by Lysidic...
متن کاملHolopelagic Poeobius meseres ("Poeobiidae," Annelida) is derived from benthic flabelligerid worms.
Phylogenetic relationships among and within the more than 70 recognized families of Annelida are poorly understood. In some cases, such as the monotypic Poeobiidae, derived morphology hinders the ability to find convincing synapomorphies that help elucidate evolutionary origins. In such cases, molecular data can be useful. Poeobiidae consists of the holopelagic polychaete Poeobius meseres, whic...
متن کاملPhylogenetic information from three mitochondrial genomes of Terebelliformia (Annelida) worms and duplication of the methionine tRNA.
Mitochondrial genomes have been useful for inferring animal phylogeny across a wide range of clades, however they are still poorly sampled in some animal taxa, limiting our knowledge of mtDNA evolution. For example, despite being one of the most diverse animal phyla, only 5 complete annelid mitochrondial genomes have been published. To address this paucity of information, we obtained complete m...
متن کاملMolecular Phylogeny of Echiuran Worms (Phylum: Annelida) Reveals Evolutionary Pattern of Feeding Mode and Sexual Dimorphism
The Echiura, or spoon worms, are a group of marine worms, most of which live in burrows in soft sediments. This annelid-like animal group was once considered as a separate phylum because of the absence of segmentation, although recent molecular analyses have placed it within the annelids. In this study, we elucidate the interfamily relationships of echiuran worms and their evolutionary pattern ...
متن کاملBone-Eating Worms Spread: Insights into Shallow-Water Osedax (Annelida, Siboglinidae) from Antarctic, Subantarctic, and Mediterranean Waters
Osedax, commonly known as bone-eating worms, are unusual marine annelids belonging to Siboglinidae and represent a remarkable example of evolutionary adaptation to a specialized habitat, namely sunken vertebrate bones. Usually, females of these animals live anchored inside bone owing to a ramified root system from an ovisac, and obtain nutrition via symbiosis with Oceanospirillales gamma-proteo...
